However, this approach might present problem if for some reason (inclement weather, for example) it is not desirable to unlock the building resulting in an unprotected facility.
The first man in feature prevents this. The schedule is programmed, and the card reader or keypad is set up so that whenever a valid credential is presented, a separate set of dry contacts actuate.
If the entry system supported multiple outputs, then the system could be refined so that only selected credentials or codes activate this output. The dry output is connected to the first man in terminals on the prime time. The DT-7 runs the schedule, but the main output will not trigger until the first time the first man in input is activated within that time zone.
For example, the timer is set to unlock at 8 a.m. on Monday, but it snows. No one shows up, so the building remains secure. Or maybe a tenant shows up, but that user does not trigger the specific output assigned to the first man in, so even though that individual is able to get into the building, the door relocks and security is preserved.

The PZ-1 is a sounder mounted on a stainless single gang plate which is used as a remote alarm sounder for exit delay or remote door prop. The sounder has two inputs, steady and pulsing, and produces a loud strident tone. It operates on 24VDC.
If two separate types of alarm are required, the steady tone can be assigned to one alarm, and the pulsing to another. You can remove the piezo from the plate and custom mount it.
Features and Benefits include:
- Remote annunciator
- Powerful Piezo sounder - 86db
- Stainless Steel Single Gang Plate: 4.5" x 2.75" [114mm x 70mm]
SECURITRON ZONE LIGHT PANEL
Securitron’s Zone Light Panel (ZLP-1; ZLP-2; ZLP-4) comes with pairs of LEDs (red and green) and is ideal for applications where high visibility indicators are desired.
Like most SECURITRON products these LED’s operate on 24VDC or 12 VDC field configurable. The LEDs can be easily removed from the switch plate and mounted as required.
The LEDs produce a very visible signal which can be easily seen at a distance during daylight. We used them indoors in areas with windows letting in sunlight, and the LEDs could be seen without a problem from the other end of the building.
Compared to discrete LEDs available from LED specialty sources, these LEDs are more cost effective and versatile.
The EEB-2 exit button is supplied with a variety of colored lenses, and an integral 30-second delay timer. Securitron offers an optional LED kit for the EEB-2 which I prefer to use as an enhanced safety feature.
When the EEB-2 is used in conjunction with the Securitron XMS REX motion sensor, it becomes an approved exit control solution, by providing a redundant means of egress:
- If power fails to the EEB, the XMS or the electromagnetic lock
- If the area fills with smoke obstructing the motion sensor, (of if the motion sensor fails for any other reason) the button still will release the door and keep it released for 30 seconds.
- Provides single motion egress.
- The added illumination kit directs attention to the switch, and the large word EXIT does not require previous knowledge.
On doors where the LAHJ does not require a push bar, but still demands free egress, these components are designed satisfy that requirement. However do not assume anything, ask the LAHJ before you install anything, and ask him how far and how high above the finished floor he would like the REX button to be mounted.
